Per I-CAR curriculum: “Some limitations or considerations for PDR repair include:

  • do not drill access holes. If holes must be cut to access the panel backside, PDR is not an acceptable option. Adding holes to a structural part can alter the structural integrity of the vehicle, creating collapse zones where none were intended.
  • other parts should not be damaged during the dent removal process. An example of this may include elongating an access hole by placing pressure on it during the dent removal process.”
